GET AN A
| Question | Answer |
|---|---|
| Autotroph | (producers) 10% of all organisms- some use inorganic compounds instead of sunlight to make food (chemosynthesis)- chemoautotrophs |
| Heterotrophs | consumers that can't make their own food |
| Examples of Autotrophs | plants |
| Examples of Heterotrophs | animals, fungi, some bacteria, some protists |
| ATP | molecule used by living things to store and transfer energy |
| Parts of an ATP molecule | Adenine, Ribose, 3 Phosphate Groups |
| Equation for ADP-> ATP | |
| Equation for ATP-> ADP | |
| Glucose | stores more than 90 times the energy that ATP does and are used to store and transfer larger amounts of energy |
| Animals storage of glucose for later | |
| Plants storage of glucose for later | |
| Problem with Van Helmont's conclusion | he concluded that plants get all nutrients from water, but did not realize the contribution of carbon dioxide |
| Chemical equation for photosynthesis | 6 CO2 + 6 H20 → C6H12O6 + 6 O2 |
| pigment | light-absorbing molecule |
| main pigment used by green plants to store energy | chlorophyll |
| two kinds of chlorophyll | chlorphyll a and chlorophyll b |
| wavelenghts absorbed and reflected by chlrophyll a | blue violet and red; green and yellow |
| wavelengths absorbed and reflected by chlorophyll b | blue and red; green and yellow |
| Carotenoid pigments | accessory pigments in plants that reflect orange, red and yellow light. -fall colors |
| Parts of the chloroplast | thylakoid, granum, stroma |
| where in the chlorplast do reactions for photosynthesis happen? | in the thylakoid membranes |
| NADP+ | one of the carrier molecules that transfers high-energy electrons from chlorophyll to other molecules |
| NADP+ -> NADPH | when nadp+ accepts and holds 2 high energy electrons along with a hydrogen ion |
| Where does the H in NADPH come from? | photosynthesis |
| light-dependent reaction | in thylakoid membranes, water is taken, split, and oxygen is released, high-energy electrons are carried to other areas of the chloroplast |
| calvin cycle | in stroma, CO2 taken in, sugars released, high-energy electrons are used from light-dependent reactions |
| molecules that participate in light-dependent reactions | h+ ions pumped into the thylakoid space |
| why does photosystem II come before photosystem I | photosystem II was discovered first |
| Another name for the Calvin Cycle | Light-independent reaction |
| light-dependent reactions require ______ | light |
| ATP and NAPH are made in ______ | light-dependent reactions |
| What happens to water during the light-reaction? | water is split to release oxygen |
| Which molecule is given off as a waste gas? | oxygen |
| Which molecules produced by the light-dependent reaction are used during the Calvin cycle? | ATP and NADPH |
| What happens during the Calvin Cycle? | ATP and NADPH provide energy to build sugars, ADP, Pi, and NADP+ are released |
| Where does the CO2 and O2 in glucose come from? | light-independent reactions |
| where does the hydrogen in glucose come from? | |
| Which factors affect the rate of photosynthesis? | temperature, light intensity, and availability of water and CO2 |
| what are the names of two pathways that allow plants in hot, dry environments to survive? | Xylem and Phloem |
| function of the cuticle and epidermis in a leaf | |
| function of guard cells in regulating photosynthesis | they control the opening and closing of the stomata, which stay open just enough to allow photo synthesis to take place, but not lose water |
| how do the reactants and products of photosynthesis enter and leave the leaf? | through the stoma |
| how is the structure of the leaf optimized for light absorption |
